Autogenerated LLM Summary
(model
llama3.2:3b
, generated one year ago):
Based on the provided data, I'll answer the question: What is the capacity of each color group when using both Native JavaScript and Lodash.js? Given the following JSON object: ```json { "cars": [ { "color": "purple", "type": "minivan", "registration": new Date('2017-01-03'), "capacity": 11 }, { "color": "purple", "type": "station wagon", "registration": new Date('2018-03-03'), "capacity": 5 }, // ... other cars ... ] } ``` Using Native JavaScript: ```javascript Object.values(cars.reduce((c, v) => { c[v.color] = c[v.color] || []; c[v.color].push(v); return c; }, {})).map(a => { return {color: a[0].color, capacity: a.map(i => i.capacity).reduce((x, y) => x + y)/a.length} }); ``` Result: ```json [ { "color": "purple", "capacity": 8.5 }, // ... other colors ... ] ``` Using Lodash.js: ```javascript Object.values(_.groupBy(cars, a => a.color)).map(a => { return {color: a[0].color, capacity: a.map(i => i.capacity).reduce((x, y) => x + y)/a.length} }); ``` Result: ```json [ { "color": "purple", "capacity": 8.5 }, // ... other colors ... ] ``` Both Native JavaScript and Lodash.js produce the same result: a capacity of approximately 8.5 for each color group (purple).
